I specifically chose a VVT engine for my swap for all the reasons mentioned. I chose an LH9 (allum. 5.3, gen 4) and the factory tune had 26* iirc of retard at part throttle. Another reason manufacturers put that much retardation in is for EGR. My swap passes smog because the VVT is considered EGR.
Doesn’t the coyote use its vvt to accomplish its egr function? Do the lt motors do that too? I would be interested and seeing the hp sweep when the cams are in egr mode vs deleting that function. I’m also guessing the egr mode doesn’t operate at wot so maybe not a change at all
I am very interested in this subject. If one was building a Dart Gen. 3 Hemi block, would it be possible to put in a big cam and keep the VVT for low rpm drivability in the Track Hawk platform.
This is the right channel. Take a look at the many Honda VTEC videos I have up-I wrote 3 books on Hondas and (I think) still have the World's Fastest Honda Civic at 226+ mph (Bonneville).
@@richardholdener1727 gen 3 and 4 LS engines are fuel injected compared to a gen 5 engine, so doesn’t fuel atomization have a effect and something to be considered. Modern diesel engines use a variable vain turbo to maximize efficiency in both top/bottom of RPM range, but if that’s not a good alternative to a stage 4 vvt cam could a longer exhaust pushrod be used with a cheep turbo
Thanks boss i was wondering this exact question

I have always wondered why people dont run vvt cams, thats one of the reasons the coyotes make so much power from a small displacement.
I’m running VVT with my big cam.
go Bri!
Pvc.
@@richardholdener1727. I definitely recommend it.

no egr at WOT

Even with VVT, a big cam isn't going to do what a smaller cam does, but it might improve drivability over just having the big cam
@@richardholdener1727 Thank you, Richard.
VTECH YO! Crap, wrong channel.

What would a vvt stage 4 cam benefit in comparison to a variable geometry turbo?
what is your question
